This note examines the role traditional input
devices can play in surface computing. Mice and keyboards can
enhance tabletop technologies since they support high fidelity
input, facilitate interaction with distant objects, and serve as a
proxy for user identity and position. Interactive tabletops, in
turn, can enhance the functionality of traditional input devices:
they provide spatial sensing, augment devices with co-located visual
content, and support connections among a plurality of devices. We
introduce eight interaction techniques for a table with mice and
keyboards, and we discuss the design space of such interactions.
